2009
On May 6, 2009, Tracy was taken out of the starting lineup, replaced by Josh Whitesell, who was called up to the Diamondbacks after hitting.356 for the Reno Aces with a.477 on-base percentage and a.552 slugging percentage. Manager Bob Melvin said Whitesell would get a chance to play every day, and that Tracy "is going to pinch hit, he's going to fill in at third and first for a while." That did not last long, however, as on May 19, not even two weeks later, Melvin had been fired as manager and the team optioned Whitesell back to Reno. A right-oblique strain that Tracy suffered May 29 led to him being placed on the 15-day disabled list. Tracy came off the disabled list after missing 27 games. Tony Clark was released in mid-July, and Whitesell was called back up for the third time in the season to replace him on July 16. Tracy said:
Obviously, I want the playing time, I want to be out there every day. Right now, there are a lot of question marks, especially for me, and some of the other guys that are on their last year of their contract or have some value to be traded, so I think we're probably at that point now where anything can happen. I wouldn't be surprised by anything.
Manager AJ Hinch spoke with Tracy, who was batting a career-low.222 with a.288 on-base percentage at the time, and Whitesell on July 17. He told them that Whitesell would get the bulk of the action at first base, starting four or five times a week "for the time being". After the 2009 season, the Arizona Diamondbacks did not pick up Tracy's 2010 option, which permitted Tracy to file for free agency.
On January 26, 2010, Tracy signed a minor league contract with the Chicago Cubs with an invite to spring training. The deal was announced on January 27, 2010. On March 29, the Cubs announced that Tracy had made the major league Cubs' 25 man roster. On May 7, Tracy was sent down to the Triple-AIowa Cubs to make room for Starlin Castro.
